Description
Summary:Species limits in the genus <em>Cistanche</em> are poorly understood, despite the plants’ long history of use in traditional herbal medicine and food across their range. Here we present a taxonomic account for the genus <em>Cistanche</em> in Iraq, where several taxa have been reported, most of them doubtfully. Using herbarium specimens, images of living material, and taxonomic literature, we found evidence of only one species occurring with certainty in Iraq: <em>Cistanche tubulosa</em>. We found no evidence for the occurrence of other <em>Cistanche</em> species in Iraq, including a putative new entity reported for the region. Our work highlights inconsistencies in the literature, and underscores the importance of examining multiple stable characters for delimiting species in the genus <em>Cistanche</em>.
